A Study on the Mechanisms of Interaction between Deep Foundation Pits and the Pile Foundations of Adjacent Skewed Arches as well as Methods for Deformation Control

Table 4

The effectiveness of each reinforcement scheme in controlling the horizontal displacement of the pile cap.

Horizontal displacement	Reinforcement scheme
	Without reinforcement	Reinforcement via isolation piles and jet-grouted piles	Reinforcement using arched walls with different heights			Setting up inclined piles with different inclinations under the pile cap
			Arched wall height of 5.15 m	Arched wall height of 9.25 m	Arched wall height of 13.2 m	Inclination of 30°	Inclination of 45°	Inclination of 60°
